SPECIFICATION forming part of Letters Patent No. 393,250, dated November20, 1888.

Application tiled March 15, 188B. Serial No. 267.208.

To all whom, it may concern:

Be itknown that I, DAVID LONG, a resident of New Haven, in the county ofFayette and State of Pennsylvania, have invented a new and usefulImprovement in Wheels of (loke- Barrows; and I do hereby declare thefollowing to he a full, clear, and exact description thereof.

My invention relates to wheels for barrows, and more' especiallycoke-barrows. These coke-barrows are for carrying very large loads ofcoke, and the strain upon the wheel and vframe of the barrow in dumpingtheload is so great that the Wheel soon becomes broken and the framespread apart, so that it can no longer be used. As now constructed,thecokebarrow wheels consist of a cast-iron wheel with a hole in the hubthereof, through which is passed the axle of wrought iron or steel, theWheel being held in position on the axle by a collar or shoulder formedon the axleshouh der, and a key driven through a hole in the axle on theother side of the hub and serving to hold the wheel against theshoulder. rIhis axle is secured to the bars of the barrow-frame by ahook-shaped bolt or strap passing down through the ends of the bars andembracing the axle, holding it againsta bearing-block on the under sideof the. bars, and permitting the axle to move laterally in the framcmoreor less. The great difficulty with this construction has been that thewheel soon becomes loose on the axle, as both the shoulder and keybecome worn to such an extent as to permit the lateral movement of thewheel on the axle, which causes a wabbliug of the wheel and increasesthe labor of pushing the barrow, at the same time causing the Wheel tosoon break from the lack of rigidity to resist the strains thrown on itwhen the barrow is dumped. In consequence, also, of the free movement ofthe axle the frame ofthe barrow is subjected to a spreading action eachtime that the barrow is dum ped,the strain in du mping coming upon thearm or side bar of the barrowr which is raised up, and as that armpresses against the spindle of the wheel the frame is pressed or spreadapart and soon becomes worthless.

The object of myinveution is to so construct the wheel that it cannotcome loose on the (No model.)

axle, but will always be rigidly held thereon, and at the same timeprovide an attachment of the axle to the framebars which will strengthenthe frame by'resisting the tendency of the latter to spread during thedumping operation.

To these ends my invention consists in certain combinations of parts,more fully hereinafter set forth.

To enable others skilled in the art to make and use my invention, I willdescribe the same more fully, referring to the accompanying drawings, inwhich- Figure l is a longitudinal vertical section of the wheel and itsaxle. Fig. 2 is a detail section of the attachment of the wheels to thebars of the barrowaframe. Fig. 3 is a detail side view of the same. Fig.4 is a view of the body of the wheel.

Like letters refer to like parts in each of the figures of the drawings.

In constructing my improved wheel the body a is made of cast metal, andis provided with the spokes b, rim c, and hub d, the latter havingformed therein on each side the central depression or recess, e, for thepurpose hereinafter explained, and a series of holes, f, around saidrecess for the bolts employed in attaching the axle or spindle to thebody of the wheel, as hereinafter explained. A wroughtmetal tireisgenerally shrunken upon the wheel to strengthen it. Secured to each sideof this wheel-body a are the spindles hh', which form the axle of theWheel. These spindles have at their inner end the enlarged flange t',which has therein a number of holes, j, corresponding to those in thehub d, and on the inner face of the ange is a centralprojection or lug,k, which tits into the recess c, and serves to center the spindle andtake the shearing or torsional strain from the bolts which hold thespindle to the hub, both the recess e and lug or projection la being`angular in shape, so sustaining all torsional or twisting strains, andthe sides of said recess and projection being beveled or inclined, sothat they are perfectly centered and all side movement is prevented whenthey are drawn together. The spindles 7L h are held to thehub d of thewheelbody a. by a series of bolts, Z, which pass through the holes j in'Iiange of the spindle ICO and the holesfof the hub of the wheel, andare provided with nuts L on their outer ends. By screwing up the nuts Ztightly the lugs k on the spindles are foi'ced firmly into the recessese, and thereby centered and lirml y secured, as above described, and anyshearing strain which comes` on the spindles will be resisted by theselugs pressing against the sides of the recess, as well as by the boltsZ. To secure' a stronger gudgeon or journal for the spindles 7L h, andavoid the necessity of making the entire spindle of wrought-iron, I castthe spindles with a wrought-iron rod, m, projectingfrom the end thereof,this rod iiaving a head, m', thereon, at a distance from the shoulderh2of the spindle, which distance is sufficient to give an ample journal orgudgeon for the spindles. Any suitable method of casting this rod m inthe spindles h h may be em ployed, and it is desirable that the rodshall extend nearly to the inner end of the spindle, so that thegreatest amount of purchase is given to the rod and the spindlestrengthened throughout its entire length.

To attach the axle to the frame of the bar row-that is, the frame whichsupports the body of the barrow--a bearing-block, a, is formed with anupwardly-proj ecting flange, a', on its upper side to fit against andbear on the sides of the side bar or arm o of the frames when thebearing-block is in place, and with a groove or concave bearing-face,a2, ou its under side for the journals of the spindle, and

\ also with vertical grooves il. on each side to forni a seat for thehOOkshaped bolt p, which holds the rod m in position in the bearing ifwhen the wheel is in place, the head m of the rod fitting outside of theblock a. XVith this construction when the barrow is dumped, the weightbeing on the bar on the lower' side of the barrow, the thrust iscommunicated from the latter to the block a by the fiange a', and as theblock n rests against the head m' of the rod m the strain or weight iscommunicated from the lower bar 0 to the rod m, and by the rod to thewheel, and through the wheel-spindles to the other bar of the frame, thestrain or weight thus tending to draw in the lower bar and through thewheel to hold the bars in proper line, and thus prevent the spreading ofthe frame.

lf at anytime the body of the wheel becomes broken, it can be removedand a new wheel inserted, and if the spindles become loose on the hubthe nut l maybe screwed up to tighten the parts iu place. Vlnconsequence of the strengthening of the spindles of the wheel by thewrought iron or steel rods m a strong and rigid axle for the wheel isobtained, which is so firmly united to the wheel that it is not liableto work loose.

Having now described my invention, what l. claim is l. In abarrow-wheel, the eombiuation,with a wheel-body having a central hubforming part thereof, of east-iron spindles attached to the side ofsaidhub,and each having a wroughtiron gudgcon extending nearly through andprojecting beyond the outer end of the spiir dle, substantially as andfor the purpose set forth.

2. In a barrow-wheel, the con'ibinatiomwith a wheel-body having a recesson each side and in the center thereof, of a spindle attached to eachside of the body, each spindle having a lug on its inner end, which fitsinto one of the said recesses, substantially as aud for the pur pose setforth.

3. 1n a barrow-wheel, the combination of the body a, having the angularrecesses on each side of the center thereof, and the spindles attachedon each side of said body, said spindles having the angular lugs orprojections r, corresponding in shape to said recesses c and fittingtherein, substantially as and for the purposes set forth.

4. ln a barrow-wheel, the combination of the body a, having the recessesc therein, the spindles l1, 71,', bolted to said bedy,the said spindleshaving lugs 7J on the inner ends, which fit in said. recesses, and arod, m, cast in the spindles and projecting beyond the outer end of thesaine to form bearings, substantiallyas and for the purpose set forth.

5. In a barrow-wheel, the combination,with the bearing-blockn, havingupwardly-projecting flange a thereon, of the gudgeon or journal m,having the head m on its outer end, and means for holding the journal inits seat in the bearing-block, substantially' as and for the purpose setforth.

In testimony whereof l, the said DA vin LONG, have hereunto set my hand.
